A cuckolded actor named Jake Scully (Craig Wasson) is invited to do some house-watching for a friend of his. Scully's peeping tom preference sends him into the middle of a murder mystery where his only ally is a foul-mouthed porn star named Holly Body (Melanie Griffith).

Highlights of the movie include nude scenes with a pre-plastic surgery Melanie Griffith as Holly Body and, in an odd twist, an appearance by Frankie Goes To Hollywood, who perform their hit song "Relax" as part of a movie that Body is filming.
